Everyone with determination having a great many uses (3-7)
I believe the answer is:
all-purpose
'having a great many uses' is the definition.
I can't tell whether this definition defines the answer.
'everyone with determination' is the wordplay.
'everyone' becomes 'all' (all people).
'with' means one lot of letters go next to another.
'determination' becomes 'purpose' (I've seen this before).
'all'+'purpose'='ALL-PURPOSE'
Can you help me to learn more?
(Another definition for all-purpose that I've seen is " Useful in many ways".)
